In Germany February 16; 1938) 12- Claims. (or. resv i The invention relates to a type. line ejecting device for matrix setting and type line casting machines permitting particularly rapid and easy 5 change of size. I-leretofo-regior example, in mabeen necessary for changing the typeline ejector not. only to remove its entirecarrier fror'n its uide arranged near the hot casting pot inathe machine frame, after undoing thehelical spring urging it into its position of rest, but thereupon it has, been necessary to unscrew two screws completely out of their screwthreaded holes'in order to be .able to insert the new type line ejector, secure it and then, together with the carrier, introduce it into the machine again and connect, it to the. tension spring holding it fast.

In contrast thereto, the'new type line ejecting d vice, which is. also advantageously applicable to machines equipped with other matrices is by means-0f. a handle, readily accessible from the rear and precludesany danger of. burning for the compositor, even in the case of a hot cast? ng pot, a light pressure against a, hand lever being sufiicient, to permit removal and reinsertion of, ejector plates without having to undo springsor screws for this, purpose or even having to remove the entire ejector carrier from its guide in the machine.

According to the invention, in the new type line, ejecting device, this object is accomplished by the fact that cams, which are pivotally mounted on the ejector carrier, slidably uided in the machine, are adapted to be operated by means of a hand lever under the action of a 7 spring which engages said lever-conveniently the tension spring that simultaneously also presses the entire ejecting device, i..e. the carrier and, ejecting plate, towards the position of rest-. and press firmly in the operative position the ejecting plate which is guided by means of slots onpins'secured to the ejectorcarrier. "ll'iesev cams may be mountedindividually on a shaft pivoted in. the ejector carrier or they may be.

made integral with said shaft. in order to en sure satisfactory sliding away of the waste, that is to say, the tang separated after cooling of the type line, it is necessaryto chamfer thejcam discs with an outward inclination so that pieces of waste cannot remain-on them or 'find their way-"between the parts of' the ejecting device Conveniently, however, in place of the shaft. carrying the cams, a bar of substantially prismatic shape pivotally mounted in the ejector carrier'by means of two lateral pivots is *employed, the'upper rear face of said bar, which chilies with matrix barsguided on wires, .it h as extends/throughoutithe entire length of' the type.

line ejector and also prevents the penetration.

Of lead cuttings, intothe ejecting device, being chamfe'red with an outward inclination in a man nei ensuring satisfactory sliding away of the separated type line tang.

' The invention is illustrated diagrammatically in'the accompanying drawing with reference to an ejecting device, selected as a constructional; 1

but in, the release position of the cams'after the ejecting plate has beenmoved away, i 5

Figurev 4 shjowsav section on the line of Figurel, Figure .5 shows the el'evationof a type line ejecting plate'removed from the device, Figure 6 shows the elevation of the carrying frame for-receiving the ejecting plate, the cam shaft having been removed, and

'Figure '7 shows the plan of a substantially prismatic bar carrying the cams.

In the bridge I (moved by the machine in a mainly vertical direction, the, frame-shaped carrier 3', receiving the ejecting plate 2, is guided by means of its two pins 4, the lowerfree ends of which engage in known manner by meansv of dove-tail grooves 5 correspondingslides 1 secured to them'achine frame 6. In the base ledge 8 of the ejecting plate 2 corresponding to the type lines to be cast'are receivingslots It (Figure 5) which are downwardly open (in the'opera tive position), are provided with chamfered edges m 9 and engage guide pins ll (Figure 6) secured to the carrier 3 and having a diameter corresponding exactly to the width of theslots Ill.. The thickness of thebase ledge 8 projects slightly beyond the top of, the guidepins ll, so that the latter are always in a sunkposition in the guide 45. slots ID of the base ledge 8 of the ejecting plate Z. These slot and pin connections Ill, ll serve for the lateral guiding of the ejecting plate 2 in its longitudinal direction, while in the operative position,- the plate 2 bears with its base ledge'8 against. the supporting edge !2 of the carrier 3. 'On the'side opposite the pins H of the carrier 3 I cams 53 are so arranged on a connecting piece l5 pivoted in the frame of the carrier 3 by'means of pivots 14,: I4 that in the operative position 55.

(Figure 2), under the action of a spring,advantageously of a tension spring l9 secured by one end to an eye I6 on the bridge I and by its other end to anarm l8 secured to the connecting piece 15 and projecting for instance through a slot I! in the bridge I, they press firmly against the by the machine, and also of holdingthe ejecting plate 2 firmly in its operativeposition (Figures 1" and 2) through the connecting piece I8, l5 by" means of the cams l3. :1

The cams it may be secureditoa common'shaft mounted in the frame of the carrier'3 ormay be, made integral with said shaft. Their. upper rear,

faces 20 are chamfered with an outward inclination so that no separated type line t'a'n'g waste 1*: will remain resting thereon but will'slide off satisfactorily. Advaritageously', asv will also be seen from the drawing, the cams l'3"'are formed as part of a substantially prismatic bar l5 connecting them together and adapted to rock aboutits end, pivots M, M in' the carrier 3,.the outwardly and downwardly inclinedrear'fafce 20 thereof,

whichextendsthroughout'the entire length of the ejecting plate 2 and 'is 'brought close up to the latter, ensuring not only the satisfactory sliding off of the separated type linej tang, but at the same lever 2i by turning which in the direction of the" time also preventing small pieces of lead from falling inbetween the parts of the. ejecting device. Mounted on the rearwardlypositionedpivot B5- IQ of the cam carrier l5, the said pivot being extended beyond its bearing'point, is a hand arrow A,in ..Figure 2 the bar 15 is rotated and the cams |3.secured toxit are moved away from the-base ledge 8 of the ejecting plate 2 against the action of the spring I 9, so that the ejecting plate may be readily removed in the upward direction. When the parts are in this position of release, it is possible without difficulty to insert an ejecting plate 2, 8, corresponding toanother size over the pins l I until it bears against the supporting edge (2 of the carrier 3, which plate, after the release of the hand lever. 2| is pressed, bythe cams l3 under the action of the spring [9 against the frame and supporting edge l2 of the carrier 3 and is there held fast in its operative position. 1 Having thus fully described the'invention what is claimed as new and desired to be secured by Letters Patent is:
